The present invention relates to improvements in pneumatic straw stackers for use upon threshing machines, and has for its principal object to provide an intermediate pipe section of relatively short length for disposition between the inner and outer pipe sec tions of the stacker, means being provided for securing the adjacent ends of the inner and intermediate sections together, the adjacent ends of the outer and intermediate pipe sections being secured in such a manner as to permit the outer section to be capable of lateral swinging movement in either direction.

A further objectis'to provide a pneumatic straw stacker which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent from the following description when taken in connection with the accompanying drawings.

In the accompanying drawings wherein like reference characters indicate correspondingrparts throughout the several views igure 1 is a side elevation of the pneumatic straw stacker embodying my invention. y i

Figure 6 is a side elevation of the intermediate pipe section. I Y

Figure 7 is a top plan view showing the manner in which the inner andj outer pipe sections are connected tothe intermediate section. a I 1 Figure 8 is a sectional view taken approximately on the line 88 of Figure 7 and- Figure 9 is a detail perspective view of the chines in the manner Well known-in the art;

The stacker includes a curved inner pipe section 2 that is supported at its lower end on the usual horizontal turn table 3. The outer pipe section is illustrated at 4 and this outer pipe section includes the telescopic tubular units which are telescoped by the actuating means shown generally at 5. As this particular feature forms no important part ofv the present invention, a detailed description thereof is not believed necessary. The present invention includes the provision of an intermediate section 6 which is of relatively short length and affords a meansfor connecting the inner opposed ends of the sections 2 and 4 together in the manner to be presently described. An outwardly extending annular flange 7 is formed at the inner or rear edge portion of the intermediatepipe section 6 and this flange 7 is provided with a series of spaced notches 8 as clearly disclosed in Figure 2 of the drawings. The notches are formed in the top portion of the flange. A flat metallic band 9 is secured around the forward end portion of the curved inner pipe section 2, it being understood of course-that the band is spaced from the forward edge of the inner pipe section so that the portion of the inner pipe section forwardly of the band may snugly fit in the rear end portion of the intermediate pipe section6 as clearly shown in Figure 8 of the drawings. The band 9 does not extend completelyaround the inner pipe section and the free ends of the band are disposed downwardly in diverging relation as indicated more clearly in Figure 3, and the free end portions 10 of the band- 9 are connected to suitable braces 11 that extend from the lower end of the curved innerpipe section 2 in the manner as shown in Figure 1.

The portion of the band that extends across the top of the inner pipe section 2 is bent to form' an inverted U-shaped bracket 12.

A grooved pulle y 13 is journaled for rotation in the upper portion of this bracket. A substantially T-shaped latch designated generally by the numeral 14 as shown more clearly in Figure 9 of the drawings has the leg portion 15 thereof vformed at its free end with an eye portion 16 through Which'extends a pin 17 the latter extending through i the opposite sides of the lower portion of the U-shaped bracket 12 whereby the T-shaped latch is pivotally secured in the bracket for vertical swinging movement. The cross'arm 14 formed at the opposite end of the leg portion .15 is slightly rounded, and thepurposethereof will be presently; apparent. When the forward end of the curved'inner pipe section 2 is fitted in therear end of the intermediate pipe section .6, and the outer edge of the band 9 is disp osedradj acent the flanged rear 1 edge. of the intermediate section, the. pivoted ,7 latchl may be swung downwardly so that the arm 15 will enter oneof the" notches 8 formed in the-flange 7-and the cross bar 18 will" be disposed against the inner face of the flangein the manner as indicated in Figures 7 and 8 of the drawings, so that the adj a-- centends of-the inner pipe section and the intermediate pipe section will be locked together against sliding movement with respect to each other; Encircling the forward end portion of the intermediate pipe section 6 is the; flat metallic band .19, the same being 'fixedly secured aroundthe intermediate pipe section by any appropriate fastening means.

' I Upperand lower brackets 20jand21respectively are secured on each side of the band 19. Each of these'brackets is formed at its outer side edge witha-vertically"disposed sleeveor knuckle 22 for a p'urpose to be presently described, and'the sleeves of each pair cured on the-band' 19.- F urthermore, the

of br'ackets are disposedin Vertical alinement. 6 Asim'ilar flat metallic band 2 3- encir-- cles the inner end portion of the outer pipesection 4 and is rigidly attached thereto. Up

per and lower brackets 24 and 25 respectively.

are-secured on each side of this band 23, and the rear side-edge portions of each of these brackets'isforined with a verticallydisposed i v sleeveor knuckle 26, the sleeves of each pair of bracketsthat are attached to the opposite sides of the band'23 being disposed in ver-r tical 'a'line'ment andbeing furthermore adapted to register with the vertically disposed sleeves of the adjacent pair of brackets sebrackets arearranged on the band 23 in such a manner as to have the sleeves 26 abutting f the adj acentsleeves of the brackets secured on the band 19, andaheaded: pin 27 extends through the registe ing sleeves 22 and'26 on one'side of thepipe sections, a similar pin 28 extending through the registering sleeves of knuckles onthe opposite sides of the pipe sections as clearly sh-o'wninFigure 4 where by to lock the adjacent ends of the outer pipe 7 section l and the intermediate pipesection 6 together in communicating relation. By

with the vertically alined sleeves on one side of the pipe sections whereby to provide a hinged connection between the outer p1pe secv removing the pin 27 the pin 28 will cooperate tion 4 and the intermediate pipe section 6 7 whereby to permit the swinging of the outer pipe section in one direction. Manifestly, byeremoving .the pin 28, and disposing the pin 27 through the alined vertically disposed sleeves onthe outer side of the pipe sections,

to the intermediate pipe section against swinging movement; A palr of angular brackets 29 and 30 extend upwardly from the 90' 1 top portion of the band 23 and supported'be alined sleeves, theouter pipe section islocked g tween the spaced vertical portions of-thesef angular brackets is-a grooved pulley 31 over which is trained the cable 32 and which cable also passes over the pulley 13 supported in the U-shaped bracket 12 that is formed at the top of the band 9 and this. cable is associated 7 with the mechanism for telescoping the sec tions of the outer pipe in-the usual manner;

A channeled lug 33 extends forwardly from thevertical portion of the lug 3O for-support ing the inner end of a longitudinally extend-- ing bar 34 which bar supports at its outer end is supported by the outer slidable unit of the pipe section 4: by the supporting band 36. It will thus be seen from the foregoing a wheel "35*over which is trained the chain a 5, and the outer end portion of the bar 34:

description that I have. provided a pneumatic'strawstacker wherein the outer pipe sec-.

tion can be readily andeasily folded against iio the inner pipe section on either side thereof, i r

and furthermore' the provision of the inter-' mediate pipe section enables thefparts" tobe readily and feasily assembled or disas'sem: bled. A'straw stacker of the abovementioned "character can be manufactured at a very low cost, and the same will at all times be positive and efficient in carrying out the purposes .for which it "is designed. While I have shown the preferred embodiment of myinvention it is to be understood that minor'changes may be made in the size, shape and arrangement 'ofparts without departing from the spirit ed claims. 1 1
